Re: [Numpy-discussion] DEP: Deprecate boolean array indices with non-matching shape #4353

So specifically the question is -- if you have an array with five items, and a Boolean array with three items, then currently you can use the later to index the former: arr = np.arange(5) mask = np.asarray([True, False, True]) arr[mask] # returns array([0, 2]) This is justified by the rule that i
